Hi All,

I am trying to set up automation for sending WhatsApp Outbound campaigns.  
The trigger & data are coming from an external App and sent through API. can anyone support or share any reference with this use case.

You can use Event based Flow campaign trigger in this case. Check out our [Flow Campaigns Doc](https://docs.yellow.ai/docs/platform_concepts/engagement/flows_campaign#user-events).
